It's beautiful year-round, but it's especially stunning in the winter.
An unusually chilly bout of weather may make the falls look like it's stopped moving, but most years, the falls are only partially frozen.
That's because the sheer power of the water keeps things moving.
In winter, about 85 million litres of water per minute tumble over the falls, hitting speeds up to 40 kilometres per hour.
The one time the falls stopped was in March 1848.
High winds on Lake Erie sent millions of tonnes of ice toward the channel leading to the falls, blocking the flow of water.
The falls were silent for 30 long hours.
